Progressing undetected for years
A team of Université de Montréal scientists tries to better understand the resilience of the brain during the asymptomatic period of Parkinson's disease - and makes a surprising finding. Have you or someone close to you just been diagnosed with Parkinson's disease? Well, chances the disease has been progressing quietly but insidiously for more than 10 years, new research shows.

Part of what makes depression so hard to overcome is that people with depression tend to behave in ways that lead to more stress in their lives-and stress in turn fuels mental illness. This feedback loop was initially thought to be unique to depression, but UBC psychology researchers recently revealed in Psychological Bulletin that it is a more widespread problem.
A stronger placebo effect for those who believe sham medical treatments are personalized
If you believe a medical treatment was developed specifically for you, it may be more effective, especially if you want to be seen as unique, according to new research from McGill University. In two studies, researchers in the Department of Psychology found that participants who thought a medical device that was really a placebo was personalized to their genetic makeup and physiology reported feeling less pain when using it, compared to those who believed it was a standard treatment.

Chemotherapy is a life-saving treatment for many cancer patients. Unfortunately, many cancer drugs also cause cancer cells to mutate, which over time leads them to become more aggressive and harder to treat. SFU Molecular Biology and Biochemistry researcher Mani Larijani is exploring an unconventional approach to address this issue and improve treatment outcomes for cancer patients.
It would be possible to predict the future performance of young players using variables other than on-ice performance. Martin Saint-Louis: never drafted. Jonathan Marchessault: never drafted. Tom Brady: drafted 199th . The cases of these three athletes, who rose to the top of their sport after being grossly underestimated by scouts, illustrate just how perilous an exercise it can be to identify promising youngsters.
Hidden gene pokes holes in preconceptions
Professor Sophie Breton and her team have discovered a hidden gene in the human mitochondrial genome. Mitochondrial DNA, with its relatively small number of base pairs (around 16,000 compared with 3 billion in nuclear DNA), was sequenced almost 45 years ago. "Once mitochondrial DNA was sequenced, it didn't take long to go through it," said Sophie Breton, a professor in Université de Montréal's Department of Biological Sciences.

Search engines and social media can forecast disease outbreaks
Researchers found association between prevalence of COVID and search queries, posts Internet search engine queries and social media data can be early warning signals, creating a real-time surveillance system for disease forecasting, says a recent University of Waterloo study. Using the example of COVID-19, researchers found there was an association between the disease's prevalence and search engine queries and social media posts.

A wildlife market on the dark web
A study has found that wild animal and plant species are being secretly bought and sold online, mainly for use in recreational drugs. An Australian research team investigating the trade in wild animals and plants on the dark web scanned about 2 million ads over five years and found nearly 3,500 were for wildlife.

A tornado that sliced through a rural area south of Didsbury, AB on July 1 is among the most powerful ever recorded in Canada. It has been rated at EF4 by Western's Northern Tornadoes Project , in collaboration with the Environment and Climate Change Canada (ECCC) Prairie and Arctic Storm Prediction Centre.
The vampire einstein
Researchers discover a single shape that tiles the plane aperiodically without reflection By Joe Petrik Cheriton School of Computer Science Just months ago, an international team of four that includes Cheriton School of Computer Science Craig Kaplan discovered a single shape that tiles the plane - an infinite, two-dimensional surface - in a pattern that can never be made to repeat.

Western researchers find unique blood plasma protein patterns in patients with prolonged fatigue, brain fog Using advanced research techniques, including a form of artificial intelligence, a team of researchers has discovered unique patterns of blood plasma proteins in patients with suspected long COVID that could improve patient outcomes.
Science, Health & Technology Alex Walls Using part of the Milky Way as an antenna, researchers have found evidence for gravitational waves that undulate over periods of years to decades by measuring changes in the tick of 'cosmic clocks', according to new research. The observations, published today in a suite of papers in The Astrophysical Journal Letters , were collected over 15 years by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Physics Frontiers Center (PFC), a collaboration of more than 190 scientists including UBC astronomers.
What controls the pathways of the Labrador Current?
Stronger winds shift water from the Labrador Current eastward, with dire consequences for marine ecosystems Changes to the flow of the Labrador Current along the coast of Newfoundland and Labrador to Nova Scotia are leading to sudden warmings or drops in the oxygen levels of the waters in several regions including the St. Lawrence Gulf and Estuary.

Vision allows brain to make predictions well before it knows what's coming, new study shows Blending math and AI, Western researchers developed neural network model able to predict individual moments in the future The moment a pitcher unleashes a fastball in the direction of Toronto Blue Jays shortstop Bo Bichette in a professional baseball game, the crowd at Rogers Centre hopes something special is about to happen.
How secure are voice authentication systems really?
Attackers can break voice authentication with up to 99 per cent success within six tries Computer scientists at the University of Waterloo have discovered a method of attack that can successfully bypass voice authentication security systems with up to a 99% success rate after only six tries. Voice authentication - which allows companies to verify the identity of their clients via a supposedly unique "voiceprint" - has increasingly been used in remote banking, call centers and other security-critical scenarios.

Nearly 70% of ready-to-drink alcoholic beverages such as cocktails and sodas are sold in containers bearing nutritional information that falsely gives these products a healthy image, reveals a study conducted by a research team from Université Laval and Public Health Ontario. In light of this finding, the study's authors believe that regulations surrounding the marketing of these products should be tightened.
An international team of scientists have used data collected by the NASA / / James Webb Space Telescope to detect for the first time ever a molecule known as methyl cation (CH3+), located in the protoplanetary disc surrounding a young star. They accomplished this feat with interdisciplinary expert analysis, including key input from laboratory spectroscopists.
